Brief Summary

Chimeric Antigen Receptor T Cells (CART) Therapy in GUYC2C postive Digestive system tumors, include colorectal cancer, gastric cancer, liver cancer, pancreatic cancer, adenocarcinoma of esophagus, cancer of the esophagogastric junction.

Ict-gc is an open, single-center study to evaluate the safety and efficacy of CAR-T-targeted therapy in patients with advanced gastrointestinal tumors.

Detailed Description

The primary objective of phase 1 is to evaluate the safety of CART regimens. The primary objective of phase 2 is to evaluate the efficacy of CART, as measured by objective response rate in subjects with colorectal cancer. Secondary objectives will include assessing the safety and tolerability of CART and additional efficacy endpoints.

Conditions

Malignant Neoplasms of Digestive Organs

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Patients with late malignant digestive tract tumor

Patients with late malignant digestive tract tumor, for example metastatic colorectal cancer, pancreatic cancer, gastric cancer and so on. because of this is a open, single arm trail, there is no control group.

Group Type: EXPERIMENTAL

gucy2c cart cells

Intervention Type: BIOLOGICAL

Patients with advanced malignant gastrointestinal tumors were injected with CART cells

11. The subjects voluntarily joined the study, signed the informed consent form, had good compliance and cooperated with the follow-up.

Exclusion Criteria

1. T cell transduction efficiency <5% or T cell amplification < 2 times after culture;

2. Participated in other drug clinical trials within 4 weeks before the start of the study;

3. Patients with hypertension and unable to obtain good control by single antihypertensive drugs (systolic blood pressure > 140 mmHg, diastolic blood pressure b> 90 mmHg, the specific conditions shall be evaluated by the researchers) have myocardial ischemia or infarction of grade I or above, arrhythmia of grade I or above (including QT interval ≥ 440ms) or cardiac insufficiency;

4. A wound or fracture in the chest or other area that has not healed for a long time;
